We rely on news     1     (learn) about things around us. However, reports on the same events contain different information. That’s because journalists may have different     2     (priority). Another reason why news reports on the same event may contradict each other     3     terms of factual details is that events in the real world are usually complicated and     4     (constant) changing. When we come across such factual differences in news reports, we should not rush to the conclusion that the news report gives false information. Instead, check when the reports     5     (complete). Because news reports written at different stages of an event could contain different information as news facts are brought to light. Therefore,     6     (check) different sources enables us to draw     7     more informed conclusion.

To sum up, it is wise to read news reports written from     8     (vary) perspectives and at different stages, which     9     (bring) us a more accurate understanding of a situation. We also need to be critical about the information we receive and remember not to blindly trust     10     we have read.

The Guardian view on academic publishing: disastrous capitalism

Scientific publishing has long been a licence     1    (print) money. Scientists need journals in     2     to publish their research, so they will supply the articles without monetary reward. Other scientists perform     3     skilled and specialized work of peer review also for free,     4     it is a central element in the     5    (acquire) of status and the production of scientific knowledge.

With the content of papers     6    (secure) for free, the publisher needs only find a market for its journal.     7     this century, university libraries were not very price sensitive. Since academic careers depend on publication, the demand for scientific publications is unbounded except by the price that scholarly libraries can     8    (force) to pay. Scientific publishers     9    (routine) report profit margins approaching 40% on their operations, at a time when the rest of the publishing industry is in an     10    (exist) crisis.

Famous British physicist Stephen Hawking,     1     mental genius (智力天才) and physical disability made him a household name and inspiration across the globe, has died at age 76 on March 14^th, 2018.

Propelled (推动) to superstar by his 1988 book A Brief History of Time, which became     2    unlikely worldwide bestseller, Hawking devoted    3    (he) to unlocking the secrets of the Universe.

Hawking refused to accept the predictions that he would only live for a few years after developing a form of motor neurone disease (运动神经元病) in his early     4    (twenty). The illness gradually robbed him of mobility (移动的能力)    5    (leave) him confined to a wheelchair, almost completely paralysed and unable to speak except through his voice synthesizer (合成器). It was with these difficulties     6     he revised the draft of A Brief History of Time which was published in 1988.

    7     (translate) into thirty languages, the book has sold over ten million copies worldwide and lives on as a science book that continues to captivate (迷住) and inspire new readers each year.

When I came into contact with the book, I did not know much about the time and space. Was there a     8     (begin) of time? Could time run backwards? …These questions may be with all of us during our childhood.     9    (lucky), Stephen Hawking shows us the time and the space, the God and a mystery. The book, A Brief History of Time, is available in paperback and I     10     (strong) recommend it. For me, books like A Brief History of Time are more captivating (迷人的) than any novel.
